TCP/IP Model Vs OSI Model

Difference Between TCP/IP Model and OSI Model In Tabular Form

Sno.	Features	TCP/IP Model	OSI Model
1	Full Form	TCP/IP stands for transmission control protocol/Internet protocol. It is named after these two protocols, being part of this model.	OSI Stands for open system interconnection. It is called so because it allows any two different systems to communicate regardless of their architecture.
2	Complexity Level.	It is comparatively simple model.	It is complex model.
3	Numbers of layers	TCP/IP model has four layers: host-to-network, network, transport and application layer.	OSI model has seven layers : physical,data link , network, transport, session, presentation and application layer.
4	Session and Presentation layer	There is no session and presentation layer in this model.	Session and Presentation layers are present in this model.
5	Service Interface and Protocols	It does not clearly distinguish between services, interfaces and protocols.	This model provides clear distinction between services , interfaces and protocols.
6	Model and Protocol Coherence	TCP/IP protocols fit well in this model as model is defined after protocols were implemented .	Protocols do not fit well into the model, because model was defined first before implementation takes place.
7	Type of Service	TCP/IP model supports only connectionless communication in n/w layer.	OSI model supports both connectionless and connection oriented communication in n/w layer.
8	Quality of Service	It does not provide quality of service.	It provides quality of service.
9	Type of Connection	In TCP one connection can be established.	In OSI model two independent full duplex connections can be established.
10	Size of Header	Minimum size of TCP header is 20 bytes.	Minimum size of OSI header is 5 bytes
11	Approach	Vertical	Horizontal
12	Model and Protocol Coherence	TCP/IP model does not fit any protocol	OSI model has a problem of fitting the protocols into the model.
